Embodiment Construction

[0010] An insulating cable material, made of the following raw materials in parts by weight (kg):

[0011] High-density polyethylene 37, EVA (vinyl acetate 40%) 15, stearyl polyoxyethylene ether 4, poly-1-butene 10, linear low-density polyethylene 24, silicon carbide powder 2, dilauric acid two Butyl tin 3, zinc oxide 3, bauxite 39, bentonite 23, accelerator DTDM 2, vinyl tris(β-methoxyethoxy) silane 3, ethyl acrylate 6, carbon black N339 15, N660 carbon black 26 , Antioxidant 1035 1. Modified diatomite 8.

[0012] Described modified diatomaceous earth is made by following method:

[0013] Put the diatomite at 460-480°C for 3-4 hours, take it out, cool it, soak it in 10-12% sodium hydroxide solution for 2-3 hours, take it out, wash it with pure water, dry it and grind it into Powder; then add aluminum nitride equivalent to 40% of diatomite weight, 4% ferrocene, 3% zirconium fluoride, 4% zinc oxide, 6% accelerator PZ, mix and grind for 30-40 minutes , and then spray isopropy...
